This is a second generation (Sanke X Showa) koi. As i said in another post the sumi have been improved, but the down side is the body shape is not good. By mean, this koi will unlikely to grow very big like most Showa do.

Hi is not deep enough is just because i never feed her an color enhancer. So, the hi you are saw is the natural hi of the koi. And the hi takes time to get deeper, but i don't think the hi on the body will fade.

I am looking for a Sanke with good growth, good body shape and small size sumi to breed with her. But i haven't found anything yet.
